COUPLING FOR GAS-TUBES AND TIDE LIICE.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed August 1', 1907. Serial No. 386,518.

To all whom it may concern:

Be it known that I, HERBERT HoLToN, a citizen of the United States,residing at Eastchester, Bronx borough, city, county, and State of NewYork, have invented certain new and useful Improvements in Couplings forGas-Tubes and the Like, of which the following is a clear, full, andexact description.

This invention relates to pipe couplings, the object being to provide acheap and eliicient pipe coupling particularly adapted for connectingthe gas tubes of pyrographic burners to gas fixtures.

My improved pipe coupling is made of wood, cheap grades beingpreferable. As the cheap or soft grades of wood are porous and wouldallow gas to escape through the pores thereof, I impregnate the samewith paraffin or other self hardening liquids, by dipping the couplinginto the paraflin when said paraffin is in a hot molten state, a rub-'her nipple being attached to the said coupling and also treated withparaflin to make its connection gas-tight. The pores of the wood willsoak up the parafiin until they are entirely filled. I then take thecoupling out and allow the paraflin to harden, whereby the coupling isrendered gas-tight by a cheap and efficient means.

To these and other ends which will hereinafter appear, my inventioncomprises the novel features of improvement which I will now proceed todescribe and finally claim, reference being had to the accompanyingdrawing, which forms part of this specification, wherein- Figure 1illustrates my improved coupling in side elevation with a portion of agas conducting rubber tube connected to the neck thereof and showing thenipple of the coupling attached to a gas tip; and Fig. 2 is a centralvertical section thereof, the gas-tip being shown in elevation.

Referring to the drawing, the numeral 1 indicates the body of myimproved coupling the body being of globe-like form and having anangularly disposed neck 2 cemented or otherwise attached thereto. Tosecure the coupling to a gas tip, as indicated by 3, I form the bodyportion 1 with a neck, as at 4, and apply thereto a nipple 5 of rubber,a section of rubber hose being preferable. When the coupling is inposition, the end 8 To convey gas to the pyrographic needle (not shown)I employ a conducting hose 7 which I stretch. over the neck 2 of thecoupling, the said neck being angularly disposed in order to prevent thehose 7 from buckling at the connecting point with said neck. The saidneck has a relatively smaller bore 9 communicating with the bore 6 ofthe body 1, whereby a small amount of gas can be conducted to theneedle. As the nipple is also covered with the paraliin, and as the hoseand nipple connections will thus be made gastight no gas can escape.

My improved wooden coupling is designed to take the place of moreexpensive couplings. The heavy line surrounding the coupling in Fig. 2and indicated by 10, is intended to illustrate the paraffin covering,which will appear on the surface after the said coupling has beenimpregnated.

Having now described my invention, what I claim and desire to secure byLetters Patent is:

A coupling for gas conductors composed of three parts, a wood body. ofglobe-like form having a reduced part forming a neck at one end thereof,said neck and body being formed with a continuous smooth bore ofsubstantially equal diameter throughout, which terminates at a pointapproximately at the center of said body, said body being formed with anangular opening which communicates with its bore, a wood neck insertedin said opening and having its free end projecting outwardly from saidbody, and a nipple formed of a section of rubber hose, said hose beingreceived over said first neck and abutting said body at its inner'endand being contracted at its outer end, said body, the inner end of thenipple and said second neck having a continuous film of a self-hardeningliquid thereon.
